7 1. INTRODUCTION What is an Engineering Drawing? Engineering drawing is a technical drawing which clearly defines and communicates a design to other interested parties. Other parties may have an interest in: Design collaboration, Manufacturing, Quality control, Marketing, Maintenance Mech 192 Computer Aided Design 2

8 Why do we need to know about Engineering Drawings? To allow our designs to develop from a thought or concept to a sketch on paper. To enable us to communicate Mech 192 Computer Aided Design 3

9 What are aims of this course? To represent our designs on piece of paper To be able to understand principles and rules of engineering drawing. To be able to represent 3D objects/parts/systems in 2D sketches. To be able to use CAD program effectively in 2D module To get the knowledge of 3D modelling of single parts and assemblies To be able to use 3D part design tools effectively. Modellling geometry of engineering systems part by part To be able to mate them into assemblies To be able to use state of the art technology Mech 192 Computer Aided Design 4
